Another voice bug

Some reason, since the update to download the recordings, the text can randomly switch between multiple voices. I usually use Bella for its most natural sounding tone, but will occasionally hear Sky and even a couple of the British voices. What’s really strange is the other voices that it randomly switches to don’t appear to be reading any of the text generated, but rather completely random lines.
The Bella voice was reading a line during an RP session where I and a character were simply relaxing and chatting in a forest, and out of nowhere the Emma voice said “Good. I know you like it.” Which seemingly doesn’t appear anywhere in the text.
